Chad's army said its forces had killed hundreds of Boko Haram militants and lost nine of its own troops in clashes in northern Nigeria on Wednesday April 1.
Army spokesman Colonel Azem Bermandoa said the fighting happened as Chadian forces carried out mopping-up operations around Malam Fatori, a town near Nigeria's border with Niger that was recently retaken from the militants.
Bermandoa said 16 Chadian troops had also been wounded.
